POWDER DREDGER OR SHAKER.

SPECIFICATION forming part of Letters Patent No. 757,912, dated April 19, 1904.

Application filed March 11, 1903.

To all whom it may concern.-

Be it known that I, CHARLES E. GRAPEWINE, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California,have invented new and useful Improvements in Powder Dredgers or Shakers, of which the following is a specification.

My invention relates to an improvement in receptacles known as shakers or dredgers used for distributing nely comminuted or pulverulent material, such as, salt, pepper, iour, meal, powdered sugar, and other like material; and the object thereof is to provide a receptacle with means for excluding moisture from the contents thereof which will also actas a stopper during shipment and a regulator for the flow of the pulverulent material when in use.

In the accompanying drawings, Figure l is a central vertical section of the top portion of my improved shaker, showing the inner part of the collar cut on the line 1 1 of Fig. 2, which is an elevation of said part. Fig. 3 is a side elevation of the cap.

A designates the receptacle of the dredger or shaker, which may be of any of the known forms and of any suitable material. I have illustrated it as made of glass and provided with a threaded exterior surface A', at the top of which is screwed a metallic collar B, the lower portion B' of which is interiorly threaded to screw upon the top of the receptacle. Above the threaded portion of the collar is provided on its outer surface with a groove B for the reception of a depressed portion D of the cap D, which when the cap is rotated passes into said groove and holds the cap from separating from the collar. The upper portion of the collar is spiral, as shown in Figs. 1 and 2. Cap D is provided with a slot D, which is on the same slant as the spiral and is so arranged with reference to the depressed portion D that when said portion is Serial No. 147,329. (No model.)

in the groove of the collar the rotation of the cap will bring said slot above a portion of the spiral, as shown in Fig l, or the slot may be entirely closed thereby. This slot is as wide as is necessary under any condition to allow the pulverulent material to pass therethrough. It will be observed that by this construction the width of the slot maybe varied at will and that when used as a saltshaker it can easily be regulated to permit the salt to pass therethrough and that there is never any danger of its clogging and that very tine or very coarse salt may be used from the same receptacle and its flow properly regulated.

If desired, the collar may be made integral with the receptacle. This will probably always be done when made of metal. When the receptacle is made of glass, I prefer to make the collar and cap of metal. If desired, the top of the receptacle could be made parallel with the base and the slot in the cap could be made so that it would be opened or closed by screwing the cap up or down on the receptacle.

HavingA described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The herein-described dredger or shaker having a top terminating in a spiral, the top having a horizontal groove for the reception of a lug or catch on the cap, a cap for said dredger adapted to fit over said top and having a limited rotary movement thereon, the cap having in its side wall a spiral slot and an inwardlyprojecting lug or catch, substantially as herein shown and described.

In witness that I claim the foregoing I have hereunto subscribed'my name this 5th day of March, 1903.

CHARLES E. GRAPEWINE.
